SELF-WEIGHING SCOOP.

Specification of Letters Patent.

Patented March 23, 1.909.

Application filed December 1908. 'Serial No. 4=65,98ll.

To all whom it' 'may concer/a.'

Be it 1Known that l, Altri-ion lil. ARNOLD, a citizen of the UnitedStates, residing at Central, in the county of Pickens and State of SouthCarolina, have invented new and useful improvements in Self-'llfeighingScoops, of which the following is a specification.

The invention relates to an improvement in self-weighing scoops, beingdesigned more particularly to present a scoop of this type in which thematerial may be readily lifted and its weight accurately determined in aconvenient and expeditious manner.

rhe main object of the present invention is the provision of aself-iiieighing scoop in which the parts are so arranged and constructedas to provide for their convenient assemblage or disconnection whendesired.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in whichlliigure 1 is a view in elevation showing the improved weighing scoop.Fig. 2 is a perspective of the spring member. Fig. 3 is a perspective ofone section of the holder. Fig. 4 is a perspective of the other sectionof the holder. VFig. is a perspective of the standard.

Referring particularly' to the accompanying drawings, my improved scoopcomprises a bowl 1, which, so far as the purposes of the presentinvention are concerned, may he of any desired size or form. The handleor upper end of the howl is formed to receive a scale standard 2,preferably squared in cross section and formed near one end with a beadprojection 3 to accurately position the standard with relation to thebowl and at the same time form an ornamental connection at this point. Near the opposite or upper end one surface ol' the standard is cutaway,as at Li, to receive an approximately U-shaped metal strip 5, one arm ofwhich projects in parallel relation to the proximate surface ol thestandard and is spaced therefrom to provide a pointer 6, for a purposewhich will hereinafter appear.

The holder for the reception of the standard is made up of twosemicylindrical sections 7 and 8 designed to he secured with their planeedges in contact to provide when the sections are assembled acylindrical memher. The contacting face of each section islongitudinally and centrally channeled to provide an approximatelyTrectangular recess l l i l i l inserting said standard 9 extendingthroughout the length of the section. T he recesses are so formed thatwhen the sections are assembled the cylindrical holder provided islongitudinally and centrally formed with a rectangular opening of a siteto slidably receive the standard 2. The upper end of each section isreduced on trie contact face in a direction transverse thc length of thesections, as at 10, so that when the sections are assembled arectangular channel is formed in the upper end of the holderI extendingtransverse the longitudinal channel. The section 7 on the contactingfaceis cut away at one side of the longitudinal channel i) to provide alongitudinally extending recess 11, .vhich opens from the channel 9outwardly through the roundedl surface of the section and extends from apoint a slight distance above the lower end of the section to a pointbelow the lower' wall of the channel 10. The rounded surface of thesection 8 is cutaway to form a scale receiving recess 12, which recessis approximately of the length of the recess 11 and opens through thatedge of the section 8 which is coincident with the recess 11 of thesection 7. ln the recess 12 is secured a scale 13 preferably `formednear each end with an elongated slot 14 through which screws 15 arearranged to tale into the material of the section 8, the slots 11i andthe relativo lengths of the scale 15 and recess 12 being dcsigncd topermit longitudinal adjustment of the scale in order to accuratelycompensate for the weight of the scoop.

The holder and standard are assembled hy in the squared opening formedlon gitudinally of the holder with the laterally extended portion of thestrip 5 resting in the recess 11 of the section 7 and the pointer 6overlying the scale 13. A cross har 16 is adapted to be inserted in therecesses 1.() of the assembled sections, from which cross har depends acoil spring 17 adapted to rest in the cored out channel of the holder,the lower terminal of the spring being formed to provide a hook 18 toremovahly engage a perforated ear 1.9 formed at the upper end of thestandard 2. lThe longitudinai movement of the standard relative to theholder under the influence of the weight of the material in the scoop isthus resisted by the spring 17, and the pointer moves over the scale 13to register the extent o'i the movement and thereby the weight of thematerial in the scoop. The holder and connected parts are supportedwithin a cylindrical casing a0 closed at top and open at bottom, thecasing being secured to the holder by screws 21 taking into openingsformed in the respective sections. rlhe cas* ing is formed with anelongated opening 23 through which the pointer (5 and scale 13 arevisible to enable the user to readily determine the weight of thematerial in the scoop.

rlhe bowl l is provided with a cover 24 of appropriate shape, which,near its rear end, is formed with ears 25 designed to be pivotallyconnected to the bowl, a handle 26 projecting from the cover beyond theears for convenient operation of the cover when de sired. in advance ofthe ears 25 the cover is designed to lit snugly in contact with theproximate edge of the bowl, and such edge of the cover is formed toprovide a bead 27 in which is secured a length of spring material 28,which beyond the ends of the bead and adjacent the ears 25 is coiled, asat 29, and terminally secured at 30 to the bowl. lThe spring acts tonormally hold the cover in closed position relative to the bowl, thusforming a closed scoop which will readily hold the material during theweighing operation.

The use of the improved weighing scoop is readily apparent Jfrom theabove description taken in connection with the drawings, it beingparticularly noted that by the removal oi the casing 20 the operativeparts oi" the scoop are readily separable for repair or otheradjustment.

Having thus described the invention what is claimed as new, is

l. A scoop including a bowl, a cover hingedly connected thereto andformed throughout its operative edge with a bead, and a spring heldwithin the bead and terminallyconnected to the bowl.

2. A scoop including a bowl, a cover hiiigedly connected thereto andformed throughout its operative edge with a bead, and a spring heldwithin the bead and terminally connected to the bowl, said springintermediate its connection to the bowl and f the bead being -formed toprovide a coil.

A weighing scoop including a scoop proper, a standard projectingtherefrom, a

pointer carried by the standard, a holderl l standard receivingopencomprising semicylindrical sections each formed with alongitudinally extending channel to receive the standard when thesections are assembled, a scale connected to one of the sections tocooperate with the pointer, and a spring member removably connected tothe sections and to the standard.

4. A weighing scoop including a scoop proper, a standard projectingtherefrom, a pointer cariied by the standard, a holder comprisingsemicylindrical sections each formed with a longitudinally extendingchan* nel to receive the standard when the sections are assembled, ascale adjustably connected to one ol' the sections to cooperate with thepointer, and a spring member removably connected to the sections and tothe sntaiidard.

5. A weighing scoop including a scoop proper, a standard projectingtherefrom, a pointer carried by thc standard, a holder comprisingsemicylindrical sections each formed with a longitudinally extendingchannel to receive the standard when the sections are assembled, a scaleconnected to one oi the sections to cooperate with the pointer, a springmember removably connected to the sections and to the standard, and acasing encircling the holder sections and secured thereto.

6. A weighing scoop including a scoop proper, a standard conne `ftedthereto, a holder comprising sections adapted to lac connected to form acylindrical body, said sections being each formed with a longitudinallyarranged channel designed to register when the sections are assembled totorni a g, the contacting edges oi the sections adjacent their upperends being formed with transverse channels. a cross bar iitting withinthe registering channels of the assembled sections, and a springdepending irom said cross bar and connected to the standard.

In testimony whereof affix my signature in presence of two witnesses.
